my mobile does not recognize the sim, i have updated the software but it still the same, what should

Do you have a specific error?

I believe that your phone is locked by the previous provider

If it is locked you need to contact the previous provider in order to be unlocked it is free bylaw

Reboot everything.
Make sure you are unlocked.
And any error or it just doesn't show ?
At last speak with support.

Defective sim. Reorder one and ask refund for old one.
